To aZZ whom it may concern.-

Be it known that I, Brennan SAVAGE, of the city and county of San Francisco, State of California, have invented an Improvement in Fire-Places; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to certain improvements in fire-place grates and mechanism connected therewith. It consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which-- Figure 1 is a front view of the grate. Fig. 2 is a side view. Fig. 3 is a vertical section.

The object of this grate is to increase the heating capacity and economical effects, and to make it more cleanly and easier to operate, while all the parts are easily accessible for purposes of repair or otherwise. I

A is the outer casing having the front B, the basket C, and the grate D. The back and sides of the basket are so made-in sections, B, that they may be easily taken down or removed for inspection without disturbing other parts of the structure.

At the rear of the fire-place is an open space, E, into which air is admitted through passages E on the sides of the grate and is there heated, and escaping upward is allowed to go out through the openings in the upper part of the front B and be discharged into the room.

In order to'obtain the best effects of the heat of the fire, I have formed the back of the fireplace with pins orlugs F, which are cast with the back, so that the outer ends project into the fire-place, as shown, while the inner ends extend back into the air-space behind the fireplace. The air is thus compelled to circulate among these heated pins and is much more rapidly heated. In addition to this space is another transverse channel, G, connecting the two side spaces, E, which extend back each side of the fire-place to the rear of the chamber. Behind the air-space is a chamber, H, in the upper part of which is the opening from the fire-place to the chimney a. This chamber H extends down behind the air-space, and by means of a passage, 1), below the grate connects with the ash-pit. Within this chamber are two dampers, I and J, which are operated by rods and knobs K K, extending out through the front at any convenient point. The damper I when closed prevents thepassage of air beneath the grate and so on up into the chimney. W'hen open, as in case of shaking the fire down or dropping the ashes into the ash-pit c, a certain draft is produced through the ash-pit and up into the chimneyflue, which carries away all dust and prevents its escaping into the room. The upper damper, J, opens or closes the direct passage to the chimney by connecting levers to the knob K. When open, it produces a direct draft from the grate to the chimney,which is necessary to get the fire fairly started, and after the fire is well started it may be closed, thus directing the smoke and heat down the rear flue, thereby saving a large amount of heat from waste.

The grate is journaled by means of pins at either end. One of these pins or journals is made with a square end to enter a similarlyshaped hole upon the end of the lever L for the purpose of shaking and dumping. From this lever a rod, M, extends out through the side of the front frame, having a knob or handle, d, by which it may be operated to shake or dump the grate when desired. The wholespace around the fire-place casing, both at sides, back, and top, receives air which is heated by contact with the casing-plates and the projecting pins at the back and flanges upon the sides, as shown, as well as by passing through the transverse opening G, before described. This heated air is all discharged into the room from the upper part of the front frame, B, which is perforated on the top and sides; or it may be conducted by a register into another room at the rear of the fire-place, or by a flue or pipes into an upper room or rooms, thus adding considerably to the effect of the grate.

The front bars of the basket are made rightangled-triangular in section, the right-angular sides forming the front and bottom of each bar, while the hypotenuse inclines downward and inward from the upper acute angle. This prevents dust from lodging upon the top of the bars and causes it to slide down into the fire, instead of falling out into the room.

The ash-pan f used with my improved grate incloses the bottom of said grate and is inclined downward and inwardly toward the bottom of an angle of from twenty to fifty de grees, and the front is curved to correspond with the form of the basket. This enables it to receive the dust and ashes from the basket or grate and discharge it by gravitation into the ash-pit below.

The front B is fastened to the masonry by means of an iron turn-buckle, w, and hooked rods y, threaded at one end with staples to receive the hook end, so that the frame can be held very firmly in place.

The sides and back of the fire-place are fitted with movable plates held together by suitable joints or fittings, as shown at 9, Fig. 3, and these may be taken out at any time to adjust the internal mechanism or to fit or take out the basket-bottom or make repairs.

The walls of the well or air-chamber in which the grate is set are to be lined with asbestos or non-conducting fire-clay, or to be lined with non-conducting or heat-reflecting material, or bright metal, so as to prevent the absorption of useful heat by the walls surrounding the air-chamber.

Having thus described my invention, what'I claim as new, and desire to secure by Letters Patent, is

1. Afire-place having the basket C and grate D, a chamber, E, extending rearwardly from the grate-front and having" passages through which air is admitted into the lower part and discharged from the upper part, in combination with a passage or flue, H, extending vertically within said air-space surrounded there by, and having a transverse passage, G-, passing through it and connecting the side airspaces, as shown, a passage connecting said smoke-flue with the upper part of the grate, a damper, J, by which it is controlled, and a secpart of the fire-place, and the lower end con-- nects with the space beneath the grate and the ash-passage opening downwardly therefrom, in combination with dampers whereby the upper or lower connections with the grate may be opened or closed, and a vertical transverse partition in the upper part of the smoke-flue, substantially as herein described.

3. A fireplace having its back and sides inclosed by an air-heating space, a supplemental vertical flue, H, within said space surroundedby thehot air thereof and having atransverse passage or open partition, G, extending through it and connecting the side air-spaces, said fiue having its upper end connected with the chimney and also with the upper part of the fireplace, and the lower end connected with the space beneath the grate and the ashdischarge opening '0, which leads downward therefrom, in combination with valves or dampers I J, whereby the draft may be directed through either the upper or lower connecting passages from the grate and around the partition G, substantially as herein described.

In witness whereof I hereunto set my hand.
